Biography
Horace Lawson Hunley was born on 20 June 1823 in Tennessee, but his family moved to Louisiana and he became a lawyer and a member of the Louisiana State Legislature. After the start of the American Civil War, he developed submarines for the Confederate States of America, and he revolutionized hand-powered submarines that were moved by a row of men cranking the submarine forwards. One submarine, H.L. Huntley, was named after him, and he decided to test the submarine during a routine exercise. The vessel sank in the water and all eight men, including Hunley, were killed; the submarine would later be raised and used in an accidental suicide bombing of USS Housatonic.
